Chris J.wrote a review of Sea To Summit Pocket Shower on November 22, 2009
yeah it is of course too small to really heat up in the sun in most conditions. yes a clear window with reflective interior would help(also making it less compact). if any of you campers out there own a stove(like me) just boil 1 or more pots of water to bring up river water temp. voila! awesome shower for clean freaks like me!
